' KNIFE Filed May 21, 1934 Patented Apr. 7, 1936 UNITED STATES PATENTOFFICE 4 Claims.

This invention relates generally to knives, and more specifically topocket knives, the predominate object of the invention being to providea pocket knife which is so constructed and arranged that the handleportion thereof is of substantially cylindrical shape.

Prior to this invention, pocket knives have been provided with handleswhich comprised separate sections of material which were secured atopposite sides of the knives. This structure resulted in the backportion of the knife structure being visible between the opposedsections of the handle portion of, the knife, which detracted from theappearance of the knife, and also it has been found that it is almostimpossible to print advertising and other printed matter on theirregularly shaped, opposed handle sections of pocket knives as formerlyconstructed.

The pocket knife disclosed herein'is provided with a handle which is ofsubstantially cylindrical shape, so that said handle completely enclosesthe sides and back portion of the blade-supporting portions of the knifestructure. Because of this arrangement the appearance of the knife isenhanced, and also a regular, substantially cylindrical handle surfaceis provided which is capable of conveniently receiving printed matterthereon, soY that the knife may be decorated or employed as anadvertising medium.

Fig. 1 is an enlarged side elevation of the improved knife.

Fig. 2 is a plan view of the knife illustrated in Fig. 1.

Fig. 3 is an enlarged cross-section on line 3-3 of Fig. 1.

Fig. 4 is an enlarged cross-section on line 4-4 of Fig. 1.

In the drawing, wherein is shown for the purpose of illustration,merely, one embodiment of the invention, A designates the improvedpocket knife generally. The pocket knife comprises a handle portion Hand what for convenience will be referred to as the blade-supportingportion, this latter portion being designated by the reference characterK and comprising opposed side plates I, between which blades 2 arearranged, and a suitable spring 3 arranged and adapted to maintain theblades in positions toV which they have been adjusted. The blades 2 areeach pivotally connected to the side plates l of the bladesupportingportion K by a hollow rivet 4, as shown most clearly in Fig. 4, thesehollow rivets also serving to connect the side plates together so as torenderthe blade-supporting portion K a unitary structure. The spring 3of the blade-supporting portion K is arranged in place in the usualmanner.

The handle portion H of the pocket knife A comprises a cylindrical body5 of suitable material which is provided with a narrow, longitudinallyextended opening 6 of the approximate width of the blade-supportingportion K of the pocket knife. At its opposite ends the cylindrical body5 of, the handle portion is provided with end portions l which are eachsolid except for an opening 8 of the approximate cross-sectional shapeand dimensions of the blade-supporting portion K. The openings 8 of theend portions 1 are of substantially the same width as the longitudinallyextended opening 6 of the tubular body 5 of the handle portion of thepocket knife and are alined therewith so that a continuous opening fromend to end of the handle portion of the pocket knife is provided. Theend portions 'l of the handle portion H and the tubular body 5 thereofare integrally formed or are suitably secured together to provide aunitary handle structure.

In producing the particular pocket knife illustrated in the drawinghereof, I construct the handle portion of pyralin or some other suitablematerial, and in assembling the blade-supporting portion K and thehandle portion H, I extend pins 9 through the hollow rivets 4 of thebladesupporting portion K, as shown most clearly in Fig. 4. These pinsare of slightly greater length than the hollow rivets, and if desiredthe pins 9 may be pivoted at their opposite ends as shown in Figs. 2 and4. When the blade-supporting portion K is being introduced into thehandle portion H, said handle portion is spread slightly at thelongitudinally extended opening provided by the openings 6 and 8. Theblade-supporting portion K is then inserted in the opening of the handleportion, whereupon the handle portion is compressed so as to force theextended end portions 9 of the pins 9 into the material of the handleportion, as shown in Fig. 4. Thus the blade-supporting portion K and thehandle portion H of the pocket knife are securely fixed together toprovide a unitary pocket knife structure without any fastening meansbeing visible at the outer surface of the pocket knife. It is obvious,of course, that various apparatus may be employed for the purpose ofspreading the of. the end members of the handle portion se that theknife may be attached to a chain or other connecting means.

As heretofore stated herein, the cylindrical shape of the handle portionof the improved pocket knife A provides a regularly curved surfaceWlriich is capable of receiving advertising and other printed matterthereon. Thus the pocket knife may be decorated by printing designmatter thereon, or the handle portion of the pocket knife may haveadvertising matter printed thereon whereby the improved pocket knife isconstituted an excellent advertising medium.

While I have described this invention as being particularly adapted topocket knives, it is to be understood that other devices which includefoldable blades might be constructed in accordance therewith. Forinstance, instead of the blade of a device constructed in accordanceWith this invention being a cutting blade, it may be in the form of afingernail file. Also other foldable blade elements might form parts ofthe improved structure Without departing from the spirit of theinvention.
